' Claims. (Cl. 43-124) This invention relates to new and useful improvements in apparatus for the prevention and extermination of insects which damage'buildings and structures, particularly, termites which come from the ground and initially bore into the lower wooden portions of buildings supported on impenetrable concrete slab or chain wall foundations built on ground.

An object of the invention is to provide apparatus so positioned and. arranged with respect to buildings of the character described to periodically spray and coat with liquid insecticides the lower portions of the wooden or other substances of buildings whichinsects and the like initially attack and damage.

Another object of the invention is to provide perforated pipes positioned and arranged horizontally through and adjacent the bottom of the void spaces between the vertical main outer and'inner vertical walls above the toe plates or other members of buildings of the character described through which pipes and the perforations thereof liquidinsecticides are forced under pressure at desired intervals to spray and coat the surfaces of the usual wooden toe plates or other members below said inner and outer vertical walls, as well as, the lower portions of said vertical inner and outer'walls, vertical wall studsor'other structures below said pipes and above said toe plates.

A further object of'the invention is to provide perforated pipes arranged and positioned horizontally through and adjacent the bottom of the multiple vertical main outer and inner walls of buildings of the character described with outermost vertical veneer walls spaced outwardly therefrom whereby the perforations in said pipes are spaced apart and disposed downwardly to spray and coat the surfaces of the vertical walls and toe plate or other. structure below said pipes between said main outer and inner walls of said buildings.

A still further object of the invention is to provide perforated pipes arranged and positioned with respect to multiple vertical walls of buildings of the character described whereby said pipes may be oriented so that the liquid insecticide forced through the perforations of said pipes will spray onto and coat the surfaces of ms inside of the outer walls and the toe plate or other surfaces or structures below said pipes.

A still further object of the invention is to provide perforated pipes'a-rranged and positioned with respect to multiple vertical walls of buildings of the character described whereby said pipes may be turned during the spraying operation to coat surfaces of the lower walls adjacent to either one or both sides of said pipes as well as the toe plate or other surfaces or structure below said pipes.

These and other objects of the invention will in part be obvious and will in part be more fully disclosed in the specification, the drawings of which show one embodiment of the invention, in which:

FIG. 1 is a side view partly sectional showing concrete slab foundation built on the ground supporting building having wooden toe plate beneath and under the ver- 3,330,052 Patented July 11, 1967 tical wall studs with inner and outer wooden walls attached thereto and outer veneer wall outside the outer wooden wall to form multiple wall spaced apart leaving void spaces therebetween through which perforated pipes are horizonatally disposed and extend to outer sides of the building; and,

FIG. 2 is a sectional view taken on line 2-2 of FIG. 1 with the wooden floor partly broken away to show concrete slab therebelow.

The invention will be understood better by a more detailed description thereof reference being had to the accompanying drawings wherein like numeraled parts herein denote like numeraled parts therein in the various views. The numeral 1 denotes the ground on which impenetrable concrete slab foundation 2 is laid which supports building comprising wooden vertical inner wall 3 and opposing vertical wooden outer wall 4 between which are void spaces 5. The concrete slab foundation 2 is impenetrable to termites boring therethrough. Between said wooden wall 4 and outermost vertical veneer walls 6 there are void spaces 7 therebetween, as well as, said building having the usual vertical opposed walls 8 'and 9 forming cross partition walls interiorly of said building with void spaces 10 therebetween. Toe plates 11 underlie all walls around the perimeter of the building as well as the cross partition walls and are attached to the concrete slab foundation 2 by bolts 12 embedded into the slab 2 with the upper end thereof extending through holes in the wooden toe plates 11 and nuts 13 threadedly screwed to the upper threaded ends thereof. A wooden floor 14 covers the concrete slab 2 between the toe plates 11 and having outer veneer wall 6 built on concrete slab foundation 2.

Pipes 15 having perforations 16 are horizontally disposed through holes 17 formed through and adjacent the lower ends of the vertical walls studs 18. The studs 18 are nailed to the top of the toe plates 11 by nails 19. Pipes 15 also extend through the void 'spaces 5 between the vertical wall studs 18, wooden inner vertical walls 3 and the outer wooden walls 4, and extend through void spaces 7 between the veneer walls 6 and the wooden outer walls 4 to create the spaces 7 therebetween which extends around the perimeter of the said wooden outer walls 4. Pipes 15 also extend horizontally through holes 20 in the wooden outer vertical walls 4 and holes 21 through the vertical veneer walls 6, and, said pipes 15 are provided with removable caps 22 screwed to the threaded ends 23 of said pipes 15. One of said caps 22 is removed from one of the threaded ends 23 of pipes 15, 26 or 28 and a threaded hollow housing 24 with swivel connection 30 is screwed to said threaded end 23 of pipes 15 which is connected to liquid pump 25. The liquid pump 25 forces liquid insecticide through said pipes 15, 26 or 28 and the perforations 16 thereof to spray and coat the surfaces to be treated to prevent and exterminate termites and the like which may attempt to enter and attack initially the wooden members of the building which are adjacent to and supported by the slab foundation 2. A pipe 26 is shown in FIG. 1 of drawings and has a bend 27 so as to extend over straight pipes 15 which extend transverse thereto. However, it is preferred that all pipes be straight so that they can be oriented by handles 29 to spray and coat the surfaces desired to be treated with the insecticide. Where all pipes are straight some of the pipes are at higher level than the pipes transverse thereto for clearance as shown, for example, by straight pipes 28 in FIG. 2 to be at higher level than tranverse pipes 15therebelow. The handles 29 are in alignment with the perforations 16 in the pipes 15 and 28 so that upon manual turning said pipes the operato'r thereof may determine exactly what surfaces are being sprayed and coated to insure coating all required surfaces. The toxic liquid insecticide is used at timely intervals in order to keep coated all wooden surfaces adjacent the concrete slab foundation 2 which are required surfaces to discourage or kill termites or the like attempting to enter and damage the wooden structure of the building. Termites are crawling organisms and the surfaces of the wooden areas adjacent the concrete foundation are thus kept coated with a toxic insecticide to prevent termites from ever entering or attacking the wooden or other materials adjacent and supported on said foundation. a

It is obvious that many changes may be made in details of construction and arrangement of the various parts without departing from the spirit and scope of the invention.

What I claim as new and desire to secure by Letters Patent is:
